On strong heating of H_(3)PO_(4) and H_(3)BO_(3) sum of oxidation numb

1.	On strong heating of H_(3)PO_(4) and H_(3)BO_(3) sum of oxidation number of P and B in the final producy obtained is:
Answer» <P> SOLUTION :`H_(3)PO_(4)overset(Delta)RARR P_(2)O_(5)(O.N. = +5)` `H_(3)PO_(3) overset(Delta)rarr B_(2)O_(3)(O.N. = +3)`
